Thanks for your comments, TD.
I didn't know sonar worked better with flat bottoms. Mine shows slopes clearly as far as I can tell while I am trolling. What happens on slopes, and is it when you are stationary or in motion?
My idea of "scan" was to tilt the tranducer angle by having it mounted on the end of flexible post that holds the new position it is moved to. Transducer would remain in the water at all times, and could be readjusted from above to new "hold" angles. If you remove the transducer from the water, you get errors due to air readings which are too close to the surface of water to be resolved with my unit. Angle adjust would be handy with the transducer pointing slightly forward when trolling, as you could see schools of fish or obstructions coming and quickly adjust your lines as needed. When you are anchored, it would be nice to see what is in the cones slightly off of your position, to see if you are missing anything. What do you think?

It would be nice to expand the cone and even go to side scan without using separate transducers.... That would make it more useful for me."
[#0000ff]Not an easy fix by moving the transducer around. They don't even work well on slanting slopes. They need to get a good straight shot at bottom...running at a 90 degree angle from the beam. If you pick up the transducer and start waving it around you get nothing...at least on the ones I have tried.[/#0000ff][/quote]
